With the ability to become monstrous for {5}{U}{U}, it gains three +1\/+1 counters and can turn a target land into an Island, potentially disrupting your opponent's mana base while boosting your own. This card fits well in control decks that utilise blue's land manipulation and can be a solid threat in the late game. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.\n\u003c!-- AI-SEO END --\u003e","brand":"Vault of cards","offers":[{"title":"English \/ Good \/ Normal","offer_id":42619470872711,"sku":"THS62-128508","price":0.11,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0276\/6900\/4423\/files\/3f942075-b285-495c-941e-6f1da48d7948.jpg?v=1776252323","url":"https:\/\/vaultofcards.co.uk\/products\/sealock-monster-theros-uncommon-62-264035","provider":"Vault of Cards","version":"1.0","type":"link"}
